In fact, everyone knows about projectors. They have been in contact with them since the beginning of the school. Every time they are used, there will be a "black room". The projectors are commonly used in indoor applications such as conference rooms, schools, exhibition halls, home theaters, and entertainment venues. There is indeed a certain gap between the price of the projector and the price of the LED display, which is why customers say that they spend a lot of money to make the LED display, and the LED display P2.5 in the conference room probably costs tens of thousands It can be achieved. If you use products such as P2.0, P1.9, and P1.8 with small spacing, it will cost hundreds of thousands or even higher due to different brands. Are conference room led displays all made of P2.5?

  The led display screen belongs to the series of electronic products, and there will be some common faults in the process of use, such as:

  1. Part of the unit board is not bright

  2. The whole screen is not bright

  3. A unit board is always on

  4. The communication is abnormal

  5. Every few lines are bright, every few lines are not bright

  6. The large screen display is normal, but the computer black screen

  Although we have summarized the common faults of the full-color LED display screen, these are the common faults of the full-color LED display, but when the response is faulty every week, the customer system of Zhengming Optoelectronics has not received such a complaint, but it is true among the maintenance customers we contacted. This phenomenon exists. The biggest reason for this is that when we purchased products, we were careless and only looked at the price and not the result of the brand. In fact, for the electrical appliances we commonly use, we would rather spend more money to buy branded products. why? Because the technology is mature and the after-sales system is also mature, we do not need to find someone to repair it every three days, and the service life is also very long. So what are the precautions when purchasing led display? Here we list a few important ones:

  1. Tube core. It is generally recommended that the LED of the indoor full-color display adopts the light-emitting diode packaged by Tuosheng Optoelectronics, and the high-end products are recommended to use the die of Japan Nichia and the United States CREE.

  2. Package form. The advantages of surface mount package 352821211010 are large viewing angle, good luminous consistency, easy automatic welding and processing, and it is the mainstream product of led display.

  3. Density. Due to the large heat generation of the indoor LED display chip and the high density of the control circuit, the point density of the commercialized LED display cannot be made very high. 5, P3, P4, P5, P6, etc.

  4. Drive mode. The driving methods of indoor led display are constant current driving, using dynamic scanning method (mainly 1/4, 1/81/16 and other scanning methods).

  5. Refresh frequency. Improve the refresh rate, no flicker or trailing in camera shooting.

  6. Other considerations, including the scale and brand of LED display manufacturers, price, use, installation location and environment, etc.
